I don’t know what to do, advice?

Today I go to see my primary care doctor, I have gained a lot of weight and I thought it was my bc pills (I’ve been on them I wanna say 2 years or longer) but over the last year or so I’ve gained a lot, I wanna talk to her about it but she had mentioned about a Pap smear and wanted to do it. (I’d rather my gynecologist do it) so I’m afraid to even mention it? What should I do?
